I've run Fedora 2 for some time. I have /dev/mapper/vg00-lvol0 460G 448G 12G 98% /src. I installed Fedora 4 on a different partition. In Fedora 2 I run umount /src vgchange -a n vg00 vgexport vg00 all run ok. I reboot to Fedora 4. I run [~]$ pvscan -v Wiping cache of LVM-capable devices Wiping internal VG cache Walking through all physical volumes No matching physical volumes found In /var/log/messages I see where the drives in the volume group are found. Any suggestion?
